Installation (continued)
PUMP INSTALLATION
1.
If a standard air over water pressure tank is used, install two bleeder orifices about 2 ft. (6 M) apart. Orifices will automatically
charge the tank with air.
NOTICE:
If a pre-charged tank is used, DO NOT install bleeder orifices. If the pump and pre-charged tank are replacing a standard
tank system, remove bleeder orifices before installing a pump in a well.
2.
To prevent losing the pump down the well, connect a safety rope strong enough to support the pump and drop pipe (minimum 5/16
in. (8 mm) twisted polypropylene or pronila rope) to the eyelet on the pump discharge. Tie off the other end of the safety rope
securely to the well seal, well cap or pitless adaptor.
3.
The discharge outlet is 1-1⁄4 in. NPT threaded. Use 100 PSI rated polyethylene plastic pipe for installations up to 100 ft. (30.5 M)
depth. Use 160 PSI rated polyethylene plastic pipe for installation up to 220 ft. (67.1M) depth. For depths beyond 220 ft. (67.1 M),
use galvanized steel pipe for the entire drop pipe.
INITIAL START-UP/NEW WELLS
CAUTION:
NEVER operate the pump with the discharge valve completely closed. The pump can destroy itself if run with the discharge shut
off (“deadheaded”) and the warranty will be void.
CAUTION:
To avoid sand-locking the pump, follow the procedure below when starting the pump for the first time. NEVER start a pump with
the discharge completely open unless you have done this procedure first.
1.
Connect a pipe elbow, a short length of pipe and a gate valve to the pump discharge at the well head.
2.
Mount a motor control box (3-wire pump) or fused disconnect switch (2-wire pump) in a permanently weatherproof place. Make
sure that controls will not be subjected to extreme heat or excess moisture.
3.
Make sure controls are in the OFF position.
4.
Connect motor leads and power supply wires to the motor control box or magnetic starter (see Wiring Diagrams). DO NOT START
THE PUMP YET.
5.
Set the gate valve on the discharge 1/3 open. Start the pump.
6.
Keep the gate valve at this setting while water pumps out onto the ground. Let it run until water is clear of sand or silt. (To check
solids in water, fill a glass from pump and let solids settle out).
7.
When water is completely clear at 1/3 setting, open the gate valve to approximately two-thirds open and repeat this process.
8.
When water is completely clear at 2/3 setting, open the gate valve completely and run the pump until water is completely clear.
9.
Remove the gate valve for permanent installation near the tank. See the figures in the Connecting to the Tank/Water System
section of this manual.
10.
Install a sanitary well seal or pitless adaptor unit, well unit, electrical conduit and surface piping according to local code
requirements that apply.
